Winter has at last arrived at the castle above the clouds!

The little wizard Wobbletooth, Princess Pustilla, Sir Turnip and Flutteric the dragon want to go ice-skating on the castle pond. But Sir Turnip accidentally shatters the ice. And so the four friends fly to the big ice lake in the snowy mountains. There, they meet the ice princess Smaragda. She is very sad because she can’t find her best friend – the snowflake Esmeralda. The little wizard and his friends set out to help her. But finding a single snowflake in the huge snowy mountains is no easy feat.
